TSS, Inc.: The Shovel Seller in the AI Gold Rush Has Exactly One Prospector

The shovel-seller trap

There is a line that shows up in every investing forum the moment a boom breaks out somewhere: in a gold rush, it was not the prospectors who got rich, it was the people selling shovels. The line feels shrewd. It lets us ride the trend without taking the bet. We are not buying the risk — we are buying the tools.

The line has a blind spot. A shovel seller does well because many prospectors buy from him. Sell to exactly one prospector and you are no longer a merchant. You are an employee holding a stock certificate, and your boss can let you go without you ever resigning.

That is the question at TSS, Inc. of Georgetown, Texas. The company assembles the server racks that run the world's AI data centers. Its revenue has grown almost ninefold since 2021. And in the first half of 2026, 99 percent of that revenue came from a single customer. Let us read the filings with the U.S. securities regulator, the SEC, together — not to talk the stock down, but to see what is actually written there.

What TSS actually does — the workbench behind the AI racks

TSS earns money in three business lines, and they differ more than the shared company name suggests.

Systems integration is the heart of the business and the reason for the market's interest. An AI server rack is not furniture you unbox and switch on. It weighs as much as a small car, draws as much power as a city block and often has to be liquid cooled. Someone has to build the components into the cabinet, cable it, test it and prepare it for shipment before it rolls into a data center. That is the work TSS does, in a hall purpose-built for it. In 2025 the line brought in $40.4 million of revenue, up 78 percent.

Procurement is the largest and least glamorous line. TSS buys hardware, software and third-party services on behalf of its customers and passes them through. In 2025 that meant $197.5 million of revenue, 80 percent of the company total. The catch sits in the annual report on Form 10-K: because most of it is pass-through, very little sticks. A good share of the business ultimately traces to U.S. federal government buying, whose fiscal year ends September 30 — which makes quarters lumpy.

Facilities management is the small, high-margin remainder: maintaining and operating data center infrastructure, roughly $7.8 million of revenue in 2025. Gross margin here ran at 60 percent in 2025, against 31 percent in systems integration.

One detail is necessary to read the revenue figures correctly. The expensive components TSS installs in the AI racks do not belong to TSS. The annual report says they are consigned. They appear neither in revenue nor on the balance sheet. TSS sells only the labor. That is honest accounting, and it explains why a company with $245.7 million of revenue needs just 286 permanent employees (as of December 31, 2025, plus roughly 64 temporary workers).

How this stock reached our desk

TSSI landed on the research list through our in-house Reddit hype scanner, flagged on August 22, 2026. Forum attention is not an argument for or against a stock. It is a reason to go and read, and we claim nothing more for it here.

What the market data shows: market value stood at roughly $248 million as of August 22, 2026, with a 52-week range between $6.87 and $21.77. High to low across those twelve months is therefore a factor of three — the kind of swing you would expect from a name with 28.2 million shares outstanding. One figure stands out: 3,962,476 shares were sold short, roughly 14 percent of all 28.2 million shares outstanding (as of August 22, 2026). So there is a group betting on a decline and a group in the forum betting the other way. Neither tells us anything about the business. Which is why we now read the filings.

The numbers over the years — honestly credited

Start with what genuinely impresses, and that is not a small thing.

That curve is real and it is earned. In 2021 TSS was a niche services provider with $27.4 million of revenue that had barely grown for years. Then the AI wave arrived, and the niche provider became a supplier to what may be the largest capital investment cycle in the history of computing. Revenue doubled to $148.1 million in 2024 and added another 66 percent to reach $245.7 million in 2025.

The balance sheet improved noticeably over the same stretch. At June 30, 2026 total assets of $175.3 million stood against $95.0 million of liabilities, leaving $80.3 million of stockholders' equity. Interest-bearing bank debt is only $16.1 million — $4.2 million current and $11.9 million non-current. Cash held $67.7 million, plus $1.8 million of restricted cash pledged as collateral for a letter of credit with the electric utility. That is not a fragile balance sheet. The accumulated deficit from earlier years shrank from $45.2 million to $41.5 million.

And now the second curve, the one that has to be laid beside it.

Revenue in 2025 rose by $97.6 million. Operating income rose by $0.556 million. Of every additional dollar of revenue, roughly half a cent survived as operating profit. That is not an accounting quibble; it is the core of the business model. The increase came mostly from procurement, where TSS passes goods through and collects a thin trading spread.

What the filings say — the uncomfortable truths

Four findings are written into the filings verbatim. We take them in order.

Uncomfortable truth no. 1: one customer, 99 percent — and 100 percent of receivables

The Form 10-Q for the quarter ended June 30, 2026 does not name the customer. It calls it a US-based IT OEM, an American maker of IT equipment. What it says about that customer is clear enough.

"No other customer represented more than 10% of our revenues for any period presented. Our US-based IT OEM customer represented 100% of our accounts receivable at June 30, 2026 and 98% at December 31, 2025."

— TSS, Inc., Form 10-Q for the quarter ended June 30, 2026, note "Concentrations"

Elsewhere the report is blunter still: "We are economically dependent upon our relationship with a large US-based IT OEM." That is not boilerplate from a risk-factor list. It is a statement in the notes to the financial statements.

What does concentration mean in practice? All the eggs sit in one basket. As long as the basket is carried, everything is fine — and the numbers show it is being carried. But there is no second basket. No other customer reaches even 10 percent.

Uncomfortable truth no. 2: the 2025 profit jump came from the tax line

In 2025 TSS more than doubled net income from $6.0 million to $15.1 million. Read that line alone and you see a company that transformed its profitability. The annual report on Form 10-K explains where the jump came from.

"Our current year income tax benefit of $7.6 million is comprised of a $7.9 million increase in the net recorded deferred tax asset driven by the release of the valuation allowance, partially offset by $0.3 million of income tax expense related to the current period operations."

— TSS, Inc., Form 10-K for 2025, "Income tax expense"

In plain terms: TSS carried loss carryforwards from earlier years that can offset future taxes. As long as it was unclear whether profits would ever return, that benefit could not be carried on the balance sheet — it was written down through a valuation allowance. Once the profits arrived and the long-term agreement was extended in December 2025, management and auditors concluded it could be recognized. The entry lifts profit once by $7.6 million. Not a single dollar changes hands. The auditor flagged the judgment as a critical audit matter.

None of this is sleight of hand; it is standard practice under U.S. accounting rules. But it means the 2025 profit cannot be extrapolated. The comparable line is one level up — pre-tax income: $6.134 million in 2024 against $7.533 million in 2025, up 23 percent while revenue grew 66 percent.

Uncomfortable truth no. 3: the factory is leased, the risk belongs to TSS

To build the AI racks, TSS fitted out a hall in Georgetown, Texas with power and cooling that no ordinary industrial building carries. Through June 30, 2026 that cost roughly $48 million. TSS does not own the hall; it leases it. The quarterly report describes what happens if the customer relationship ends.

"Our customer could terminate the agreement if we were to materially breach the agreement, leaving us with the financial obligations of the lease and debt service regardless of whether we had revenues sufficient to cover those costs."

— TSS, Inc., Form 10-Q for the quarter ended June 30, 2026, management's discussion

The other side of the ledger deserves equal weight. The agreement was extended by two years in December 2025, with automatic one-year renewals, and it provides for fixed monthly payments that TSS believes cover the majority of facility and debt service costs. If the customer terminates for convenience, the 2025 annual report states it remains obligated to pay the fixed monthly charge and only the minimum volume commitments fall away. That is materially better protection than the sentence above suggests on its own.

What remains is the structure. TSS carries $22.7 million of lease liabilities (June 30, 2026), $16.1 million of bank debt and $45.9 million of property and equipment — assets worth considerably less outside this one customer relationship. On top come fixed power charges of roughly $192,000 per month (per the 2025 annual report), incurred whatever the rack volume.

Uncomfortable truth no. 4: profit booked, cash gone

In the first half of 2026 TSS reported $3.7 million of net income. Over the same period, operating activities consumed cash.

"The $16.0 million year-to-date net decrease in cash and cash equivalents was primarily attributable to a net use of $7.3 million in operating activities, reflecting largely the $3.7 million net income, net of $11.0 million of cash related to paydowns of our accounts payable, increased inventory purchases, and the reduction of our deferred revenues period-over-period."

— TSS, Inc., Form 10-Q for the quarter ended June 30, 2026, "Liquidity and Capital Resources"

A half year of negative operating cash flow is no alarm bell in a project business — 2023 already showed minus $8.3 million, and 2025 then delivered plus $34.9 million. But the direction is unmistakable: cash fell from $85.5 million to $67.7 million. The $17.8 million gap is $1.8 million wider than the $16.0 million quoted above — exactly the amount set aside as restricted cash for the letter of credit, which therefore no longer counts as free cash. To understand the mechanism, look at deferred revenues, which dropped from $13.9 million to $2.8 million. Advances that filled the till a year ago have now been worked off.

The revenue side belongs to the same half year: $90.5 million against $142.9 million a year earlier, down 37 percent. The reason is explainable and partly deliberate. Low-margin procurement fell 53 percent to $58.2 million, while systems integration grew 65 percent to $28.0 million and facilities management 44 percent to $4.0 million. Gross profit therefore held at $16.8 million, up 2 percent. Still, a 37 percent revenue decline is a 37 percent revenue decline, and anyone buying the stock as a pure AI growth story should know about it. For 2026 the company reaffirmed, in its press release of August 13, 2026, adjusted EBITDA at the upper end of a $20 million to $22 million range.

Valuation: a little over one year of sales

Let us set the orders of magnitude — without a daily price, which will be a different number the day after publication anyway.

At roughly $248 million of market value (as of August 22, 2026) and $193.3 million of trailing twelve-month revenue, the price-to-sales ratio is about 1.3. For a services business with a single-digit operating margin that is not a demanding number, and it sits well below what the large names of AI infrastructure cost. Strip out net cash ($67.7 million against $16.1 million of bank debt at June 30, 2026) and enterprise value comes to roughly $196 million, a little over one year of sales.

The price-to-earnings ratio is trickier. Arithmetically it stands just under 17, based on trailing twelve-month earnings of $0.52 per share. That figure still contains the fourth quarter of 2025 with its tax benefit. Take the first half of 2026 instead ($0.13 per diluted share) and annualize it, and you arrive at roughly $0.26 of annual earnings and a multiple near 34. Both numbers are correct; they simply answer different questions. Price to book stands at roughly 3.1, on a book value of $2.80 per share.

The professional view is thin and bullish: two analysts cover the name, both with buy recommendations and an average price target of $16.50 (as of August 22, 2026). With two voices, a consensus is above all one thing — a small sample. Readers who want a broadly covered company from the same AI supply chain as a yardstick will find one in our Nvidia stock analysis; that is the other side of the same arithmetic.

Upside and risks at a glance

What speaks for TSS:

• Revenue grew from $27.4 million in 2021 to $245.7 million in 2025 — the company sits at a point in the AI supply chain where real building happens.
• The shift toward higher-margin work is measurable: systems integration grew 65 percent to $28.0 million in the first half of 2026 and facilities management 44 percent to $4.0 million, holding gross profit flat despite a 37 percent revenue decline.
• The balance sheet carries: $80.3 million of equity, $67.7 million of cash and only $16.1 million of bank debt at June 30, 2026, with all credit covenants met at the balance sheet date.
• The long-term agreement was extended by two years in December 2025 and repriced for higher power consumption; it provides for fixed monthly payments and minimum volumes.
• A second leg with the same customer is forming: since May 1, 2026 TSS has been running a warehouse for it in the previously idle Round Rock hall, contracted through March 31, 2029.

What speaks against it:

• 99 percent of revenue and 100 percent of accounts receivable come from one customer (Form 10-Q for the quarter ended June 30, 2026). The filing itself uses the words economically dependent.
• Operating income is flat: $5.766 million in 2024 against $6.322 million in 2025, on $97.6 million more revenue.
• The 2025 net income contains $7.6 million of tax benefit that will not repeat.
• The first half of 2026 consumed $7.3 million of operating cash; cash fell $17.8 million and deferred revenues by 80 percent.
• Roughly $48 million is sunk into a leased hall, alongside $22.7 million of lease liabilities and fixed power charges of about $192,000 per month — costs that accrue with or without orders.
• Under the existing shelf registration TSS could raise a further $94.3 million without a new authorization — roughly 38 percent of market value.
• A good share of the procurement business depends on U.S. federal budgets; shutdowns push orders around.

A human conclusion

Back to where we started. The shovel seller in the gold rush is a good image precisely because he does not need to know who finds the gold. He sells to everyone. His risk is spread without him having to do anything about it.

TSS is that shovel seller — with exactly one customer. The workshop is good, the work is in demand, the client is solvent and contractually committed. But the $48 million sitting in that leased hall was spent for this client and no other. That is not diversification. It is a marriage without a prenuptial agreement, in which one partner built the house and the other pays the rent.

Then comes the second trap this kind of story sets. You look at the revenue curve and infer the profit curve. At TSS the two diverge. An extra $97.6 million of revenue produced an extra $0.556 million of operating income. The handsome 2025 net income owes half of itself to a tax entry that will not repeat. And in the first half of 2026, a booked profit of $3.7 million came with $7.3 million of cash going out the door.

None of this makes TSS a bad company. The balance sheet is healthy, the business is profitable, the shift toward higher-margin work is visible in the numbers. It simply makes the stock something other than the label "AI infrastructure" promises: a bet on a single business relationship, wrapped in a growth story.

Anyone willing to take that bet should see it for what it is — and keep an eye on the one number everything hangs on: the largest customer's share in the next quarterly report. What you make of that is your decision. And that is exactly as it should be.
